Like many of their mid-90s ambient peers, Lamb had to battle the perception of their music as tasteful dinner-party stuff. So it's odd their comeback record (duo Lou Rhodes and Andy Barlow re-formed in 2009) should do so little to shed that reputation. Fashionably distressed beats, washes of strings, cosmic "What does it all mean?" musings, 5 sticks pretty closely to the template established at the height of mid-to-late-90s chill-out. It's elegantly done and Rhodes's witchy vocals jar at least slightly against the prevailing smoothness, but there's nothing here sufficiently challenging to give anyone indigestion.
